“…The ATA induction accelerator created a 10-kA, 50-MeV electron beam with a 200 induction cells operating at 5 Hz, with burst mode capability up to 1 kHz. The ferrite loaded ATA cells have a 0.23-m inner diameter, smaller than the size of the multibeam test columns, therefore it becomes necessary to add the voltages of the cells on either side with a metal rod, as was done in previous induction linacs to furnish a high voltage pulse to an injector (e.g., RTA injector [72]). The accelerating gap and column itself should include the principal features of a driver: plates with multiple beam-hole apertures connected to the insulating column, and provisions for exploring baffle geometries.…”

We describe near-term heavy ion fusion (HIF) research objectives associated with developing an inertial fusion energy demonstration power plant. The goal of this near-term research is to lay the essential groundwork for an intermediate research experiment (IRE), designed to demonstrate all the key driver beam manipulations at a meaningful scale, and to enable HIF relevant target physics experiments. This is a very large step in size and complexity compared to HIF experiments to date, and if successful, it would justify proceeding to a demonstration fusion power plant. With an emphasis on accelerator research, this paper is focused on the most important near-term research objectives to justify and to reduce the risks associated with the IRE. The chosen time scale for this research is 5-10 years, to answer key questions associated with the HIF accelerator drivers, in turn enabling a key decision on whether to pursue a much more ambitious and focused inertial fusion energy research and development program. This is consistent with the National Academies of Sciences Review of Inertial Fusion Energy Systems Interim Report, which concludes that ''it would be premature at the present time to choose a particular driver approach. . .'' and encouraged the continued development of community consensus on critical issues, and to develop ''options for a community-based roadmap for the development of inertial fusion as a practical energy source.''

Experiments to study beam dynamics for Relativistic Klystrons (RK) are being performed with a 1-MeV, 600-A induction accelerator beam. The RK is a RF Power source based on induction accelerator technology and conventional resonant output structures. Capable of generating 100's of MW/m at frequencies up to K-band, the RK has been proposed as a driver for a future linear collider in one version of a Two-Beam Accelerator. A critical feasibility issue remaining to be demonstrated is suppression of the transverse instability of the drive beam. This kiloampere beam must transit about a hundred resonance output structures and many hundreds of induction accelerator cavities for the RK to achieve competitive efficiency and cost with respect to other proposed power sources. The RK's strong focusing used to contain the beam in the small aperture resonant structures, repetitive geometry, and reacceleration allow the resonant output structures to be spaced at a betatron phase advance of 360°. This phase advance (or any integral multiple of 180°) is beneficial in linear accelerators as the instability growth changes from exponential to linear. In our experiment the beam is contained in a solenoidal focusing channel, RF cavities are spaced every 60 cm, and growth in the transverse motion is measured as a function of phase advance. Details of the experiments and results are presented.
